About the P01 Project

Aging citizens are required to make complex financial, health and long-term
decisions as they prepare for and then enjoy increasingly long periods of retirement.
Moreover, as people age, there is a mismatch between the complexity of the decisions they
face and the sometimes sudden, sometimes gradual cognitive declines that accompany aging.
This project will develop new data that combines objective measures of behaviors and outcomes
relating to wealth and portfolio choice, subjective measures of expectations, preferences,
affect, measures of financial knowledge, and measures of cognition. By combining measurements
across these domains, the project will develop a fuller understanding of the financial
decisionmaking and behavior of older Americans.

The project will also advance the methodology for studying the behavior
and decisionmaking of older Americans by combining data from several modes: large-scale
surveys conducted by mail, Internet, and telephone; laboratory experiments; cognitive
interviewing; administrative records. Linking data for individual observations across these
measurements modes will provide the fullest possible picture of the decisionmaking and
behavior, as well as enabling assessment and improvement of the methods of measurement. The
methods advanced by the project for studying older Americans' financial decisionmaking will be
extended to their healthcare decisionmaking.
